BT134W-600D,115

Overview

The BT134W-600D,115 is a sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT-223 surface-mount package with four pins (three terminals plus a tab). The device supports an RMS on-state current of 800 mA and withstands a rated repetitive peak off-state voltage of 600 V. It features a non-repetitive surge current rating of 10 A and a maximum holding current of 10 mA. Gate triggering requirements include a maximum voltage of 900 mV and a maximum current of 4 mA. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Sensitive gate architecture designed for direct interfacing with low-power drivers such as microcontrollers.
• Four-quadrant operation capability ensuring reliable switching across all gate signal polarities.
• Planar passivated construction provides robust performance in surface-mount applications.

Applications

• Lighting control systems requiring low-power gate drive interfaces.
• Solid-state relays utilizing sensitive gate triacs for isolation.
• General-purpose AC power switching circuits compatible with digital logic outputs.

Procurement Notes

Verify the specific suffix 'D' against official manufacturer documentation to confirm exact electrical tolerances and testing criteria. Ensure the ordering part number matches the required sensitivity class and thermal characteristics for the target application environment.

Selection Notes

Select this component when a surface-mount solution is required for AC loads up to 800 mA RMS. The sensitive gate specification allows compatibility with standard logic-level outputs without additional buffer circuitry. Confirm that the 600 V blocking voltage meets the peak line voltage requirements of the intended system.

Part Context

This part belongs to the BT134 series of four-quadrant triacs from WeEn Semiconductors. The series offers various voltage ratings and current capacities in both through-hole and surface-mount packages. The BT134W variant specifically addresses the need for compact PCB layouts while maintaining industrial-grade reliability.

Replacement Considerations

Cross-reference with other sensitive gate triacs in the SOT-223 package having similar 600 V and 800 mA ratings. Verify pinout compatibility and gate trigger parameters before substituting with parts from other manufacturers.
